"If Lewandowski should come to us, I would be pleased," the 21-year-old told Bild.

"Robbie and I had a very good understanding at BVB. He is an exceptional striker!"

The Germany international also praised Dortmund star Henrikh Mkhitaryan, who was signed as his successor by Jurgen Klopp this summer when Gotze left for €37 million, and suggested he will be an asset for the club in Europe especially this season.

"I think he's doing well," he added. "You can see that he can play. I have noticed he will be positive in the Champions League for Dortmund [in particular]."

Dortmund defeated Bayern 4-2 in the DFL-Supercup but Guardiola's side can get revenge on the Schwarzgelben on November 23 when they visit Signal Iduna Park once again.
